To (HZ whom it may concern:

Be it known that l, Tm'smx I. Busters, a citizen of the United States, residing at Readshoro, in the county of Benningtou and State of Vermont, have invented certain new and useful improvements in Apparatus for Producing tarbon; and I do hereby declare the following to be a full. clear, and exact description of the invention. such as will enable others skilled in the art to which it apper t-ains to make and use the same.

This invention relates to improvements in apparatus for producingcarbon for electrical purposes, and particularly for the purpose of forming electrodes for arc-furnaces or the like.

.lt consists in certain novel constrtmtions,

combinations, and arrangements of parts; as will be hereinafter lully deserihct and claimed.

in the accompanying drawings, Figure 1 is a longitudinal central section through a com bustion chamber or furnace constructed in accordance with the presentv invention. Fig. 2 is a similar view, but showing the apparzv tus arranged for increasing the thickness of the carbon formed therein.

The apparatus forming the subject-matter of the )rcsent invention is designed for use in properly collecting the carbon products of combustion from an oil-[lame and so collecting the same that it may he formed into various articles for electrical use, and particularly for use as electrodes such as are commonly employed in arc-furnaces, electric lights, or other similar apparatus.

In the drawings one form of apparatus is shown which has been found a simple and yet effective means for producing the desired result, and in the said drawings 1 indicates a closure forming a combustion chamber or furnace, the said closure being preferably formed of fire-resisting material-such, for instance, as fire clay, brick, or the like. The furnace is formed with an outlet-aperture, as 2,..in one or more of its walls. Mounted in one portion of thc' furnace is asuitable oilburner 3. The oil-burner is preferably ar-- walls of the. furnace,

ranged so that its nozzle projects throu b one of the walls of the furnace, and whi c the burner may be made in any desired style it is preferably so consi ructed that oil. may be fed to the burner through a pipe 5. The burner may be controlled by any suitable valve mechanismas, for instance, the ordinarv needle-valve 6. The air is delivered through the burner in such form as to take up the oil fed thereto and spray, comminute, or atomize the same within the furnace structure 1'. A sufficient force of air is employed to carry the jet well across the furnace and to force the same in an ignited state to impinge against the opposite wall or end 7 of the furnace. The furnace is so constructed that the (Ollecting-surl'ace 7 may be movable with relation to the burner 25, for the carbon will only collect upon the collecting-surface when itis arranged at a certain distance with res ect to the burner, the distance being controlled by the pressureof the air employed in spraying the oil and the distance. to which such pres sure carries the jetfrom the burner, It is also essential that thecollecting-surface may be. moved from time to time bacl: from the burner, so as to thicken the deposit formed thereon. It is convenient to form the collecting-surface in the shape of one of the To secure the best results, also, the wall 7 when put in osition in front of the burner 3 should be sea ed by clay or other lire-resisting material applied in a. plastic condition and allowed to harden, so as to preventuny outlet adjacent to the collecting-surface for any portion of thoblast of air and oil and to hold the wall in place. After the wall has been put into place and the jet has been allowed to impinge upon the same the carbon will begin to collect thereon, forming a solid and homogeneous mass 11 noximately of the shape indicated at 8 in Fig. 1. When the mass has been formed and iiled up toward the burner to a certain degree,

it is found that it will cease to form and itis necessary to move the wall I farther from the burner, As shown in Fig. 2, tlns is generally accomplished by placing in a plastic sticky' heat without deterioration or being detriduced, as at 11,

t lcctrical pur roses,

condition a layer or coat of fire-resisting clay or similar material, as 9, upon the inner face of the wall 7 around the carbon mass 8 and to a suitable thickness with respect to the said mass. A portion of the mass, however, is permitted to project beyond the surface of the clay, as shown at 10 in Fig. 2, so that the additional mass or layer of carbon which is next to be collected will be formed upon the face of the first mass and will be homogeneous therewith. After the wall 7, with its coating of fire-clay, has been placed in position opposite the burner, the clay hardening and cementing the wall in position, the process of collecting the carbon continues, a second mass or collection of the same being prothe'previous mass. A continued setting back of the Wall 7 and the thereon will permit of large c uantity of homogeneous carbon of a size suitab e for shaping and cutting various objects, such as electrodes or carbon pencils and the like. If it is desired to spread the mass of carbon collected over a greater surface upon the collecting plate or wall, the said plate may be moved laterally either by raising or lowering the same, as indicated at 12 in dotted lines, or by moving it to one side or the other, so as to bring different portions of the inner face of i said collector op osite the burner. It will thus be evident t at any structure in which the collecting-surface may be moved to differcnt oints opposite the burner and may successively move away from the same for accumulating the mass of carbon to the desired thickness will be within the spirit of the present invention.

When the mass has been formcd upon the inner surface of the collector or wall 7, it is removed therefrom and formed by cutting, sawing, grinding, or otherwise shaping the same into various articles-as, for instance, electrodes, pencils, or the like-for electrical arc use or into receptacles of any kind for holding materials to be acted upon in an arc. find that the carbon reduced in this appal'atus is cspecially wel adapted for the production of carbon electrodes for arc-furnaces, since it is a goodwonductor of electricity and is capable of withstanding intense degrees of mentally affected in any Way.
